Description
Verfahren zur Herstellung eines Farbstoffes der Azinreihe. Gegenstand des vorliegenden Patentes ist die Herstellung eines Farbstoffes der Naph- thophenazinreihe. Man erhält denselben da durch, dass man auf ein Gemisch aus der 4 . 4'- Diauri tto - 3'- methyldiphertylamin -2-sul- fonsäure und der 1.3-Di-p-anisidinonaphtha- litr-8-sulfonsäure in einem Verdünnungsmittel ein Oxydationsmittel einwirken lässt.
<I>Beispiel:</I> 450 Gewichtsteile 1.3-Di-p-anisidinonaph- thalin-8-srrlfortsärrre und 293 Gewichtsteile 4.4'-Diarnino-3'-niethyldiphenylamin-2-sulforr- säure werden mit 7000 Gewichtsteilen 50%- igeri Alkohols und wenig Ammoniak in schwach alkalische Lösung gebracht und durch diese Lösung bei 85-40' C Luft geleitet. Nach beendeter Farbstoffbildung wird auf 60 0 C erwärmt, mit 350 Gewichts teilen Kochsalz versetzt und kalt gerührt.
Der Farbstoff wird abgesaugt, mit einer mit Kochsalz gesättigten 50 % igen Spritlösung gewaschen und getrocknet. Man erhält ein bronzeglänzendes Kristallpulver, das in Was ser mit blauer, in konzentrierter Schwefel säure mit grünblauer Farbe löslich ist. Der Farbstoff färbt Wolle und Seide grünstickig blau. Die Färbungen auf Wolle sind gut wasch-, walk-, seewasser-, alkali- und licht echt, die Färbungen auf Seide wasch- und wasserecht. Alle Färbungen haben auch sehr gute Abendfarbe.
Process for the preparation of an azine series dye. The subject of the present patent is the production of a dye of the naphthophenazine series. The same is obtained by referring to a mixture from the 4th 4'-Diauri tto - 3'-methyldiphertylamine -2-sulphonic acid and 1,3-di-p-anisidinonaphthalitr-8-sulphonic acid in a diluent allows an oxidizing agent to act.
<I> Example: </I> 450 parts by weight of 1,3-di-p-anisidinonaphthalin-8-srrlfortsärrre and 293 parts by weight of 4.4'-diarnino-3'-niethyldiphenylamine-2-sulforric acid are mixed with 7000 parts by weight of 50% - igeri Bred alcohol and a little ammonia into a weakly alkaline solution and passed through this solution at 85-40 ° C. air. After the dye formation has ended, the mixture is heated to 60 ° C., mixed with 350 parts by weight of sodium chloride and stirred while cold.
The dye is filtered off with suction, washed with a 50% strength spray solution saturated with sodium chloride and dried. A shiny bronze crystal powder is obtained which is soluble in what water with blue, in concentrated sulfuric acid with green-blue color. The dye dyes wool and silk a greenish blue. The dyeings on wool are washable, milled, seawater, alkali and lightfast, the dyeings on silk are washable and waterfast. All colors also have a very good evening color.
